Application filed November 10, 1914. Serial No. 871,300.

a T (ZZZ whom it may concern: 1

Be it known that I, ADAMs MURPHEY MCDONALD, a citizen ofthe United States, residing at Davis, in'the county of Tucker and State of West Virginia, have invented a new and useful Hose-Clamp; and I do herea by declare the following to be a full, clear,

and exact description of the invention, such as will enable others skilled-in the art to which it appertains to make and use the' In practical fields the details of construc-' tion may necessitate alterations, falling within the scope of what is claimed. v The invention comprises further'features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

In the drawings Figure, 1 is a perspective of the improved clamp as applied to a hose. Fig. 2 is a longitudinal sectional view on line 22 of Fig. 1. Fig. 3 is a transverse sectional view on line 33 of Fig. 1. Fig. 4: is a detail perspective view of the clamping ring and the screw threaded shank. Fig. 5 is a detail view of the U-shaped clamp. Fig. 6 is a view in elevation of the ring clamp and the U-shaped clamp shown in Fig. 1. Fig. 7 is a perspective view showing another form of the hose clamp. Fig. 8 is a sectional view through the formcof hose clamp shown in Fig. 7.

Referring to the drawings 1 designates the substantially ring shaped clamping member, which is provided with a laterally extending screw 2 having a nut 3. One half, which is designated by the numeral 4, of the ring clamp is semi-cylindrical, the

- other half 5 is substantially elliptical as shown. A U-shaped clamp 7 is provided, in the curved arch 8 of which an aperture 9 is constructed, through which the screw j passes, when the U-shaped clamp arches the ring clamp. The U-shaped clamp is provided with segmental curvededges 10, which merge into round corners 11 at the ends of said U-shaped clamp.

Copies of this patent may be obtained for In Figs. 7 and 8 .the'segmental curved edges contact for their full length with the hose, thereby clampingthe hose upon one side tightly against the nozzle or other con.-

nection, the ring clamp acting to tightlyclamp the other Side of the hose;

In Figs. 1 to 6 inclusive'it is apparent-that the ring clamp is provided with oppositely arranged spring arms 12, which are split from the ring as shown, and are designed to ride against the segmental curved edges of the U-shaped clamp; Thefree ends of said arms are tapered in their thickness so that the hose will neatly fit in contact with the arms and a portion of each segmental curved part. Said spring arms also act to prevent the hose from bulging adjacent the round corners of theiU-shaped clamp, which bulging is shown inFig. 7. 7

From the foregoing it will be noted there has been devised a simple and improved hose clamp, adapted for making various kinds of hose connections.

Thenut 3 acts to clamp the U-shaped member in place. 1 p I The invention having been set forth, what is claimed as new and useful is': p i

A hose clamp comprising a ring clamping memberhaving a laterally extending screw,

the lower half of the ring clamping member opposite the screw being semi-circular, the other half adjacent the screw being partially elongated or semi-elliptical, a U- shaped clamping member having an apersemi-elliptical portion of the ring, the semiture in the arch thereof to receive the screw, said U-shaped clamping member arching the circular portion of the ring havlng oppositely arranged-springarms, said U-shaped clamp having its side portions provided with segmental curved edges to engage the oppositely arranged spring arms to press them in engagement with the hose, which passes through the ring clamp. v

In testimony whereof I have signed my name tothis specification in the presence of two subscribing witnesses.

ADAMS MoDONALD.
